Troon North is very strong, and probably the best of the
bunch.
The two courses at the Boulders are fine for golf, but they
offer some of the best scenery you'll see anywhere (not on
an ocean!). Worth the trip.
After listening to all the hype and then plopping down $360 for my wife and I to play, the Grayhawk Talon course was
one of the biggest disappointments in my life. But, I did
get two new copies of Murphy's book!
Also got the bait-and-switch at the Wigwam. Beware! I
called to make a tee-time on their Gold course. I was given
one. When my wife and I made the hour drive to get there,
we paid our $300 or so, and were sent instead to what they
claimed is their "second-best" course there, the Blue. After
being covered in dirt by a dust-storm, and being subjected
to this cow pasture, I vowed never to return to this place.
Happily, I haven't.
TPC at Scottsdale, while not the greatest course in the
world, is certainly a fun time, and offers you the chance
to try to drive a green (like the big boys) and play the
course that the pro's play every year.
